Patient's question:
After the surgery for congenital preauricular fistula, there is persistent redness, swelling, and pain. Should the surgery be redone? What is the cost? What kind of assistance is needed: Should the surgery be performed? What is the cost?Doctor's answer:
Got an infection of preauricular fistula, asymptomatic cases do not require treatment. If there is an infection and inflammation, it should be treated with antibiotics and other anti-infection therapies, or abscess incision and drainage, local dressing changes, etc. Wait until the infection is suppressed and the local area is fully healed before performing the fistula resection. Before the surgery, inject a little methylene blue into the fistula and insert a probe into the lumen as an inducement. Then completely remove the black fistula or its branches. If residual fistula parts become infected, it will be very difficult to perform surgery again.
